Might have to drop tank and see if the little filter is on or maybe lose line in tank or junk new pump.

This is the second pump we got one was 30 psi n the W engine requires a 45 psi pump. So went back and got the right one for the truck. We dropped the tank pry 4 or 5 times and rechecked out work n only thing I can think of is it needs a new fsu unit, but what makes me think it doesn't is I drove the truck to the destination about 5 miles away where we could work on it and the truck ran fine with the same fsu in it. We dropped tank and checked screen filter n everything is connected proper. Still not even getting gas pressure or gas movement threw the main gas line...

fuel pup relay is bad it controls the pump from start position to run position of your ignition switch basically it starts the pump running before you start the engine and afterwards it runs the pump off of a engine sensor not direct power
